Although inclement weather sometimes obscured views of Lokon-Empung’s Tompaluan Crater, PVMBG reported that during 10-16 December observers at the post in Kakaskasen Tomohon (North Sulawesi, 4 km from the crater), saw Seismicity fluctuated, but the seismic spectral amplitude measurement (SSAM) showed a gradual and significant increasing trend over the previous 3-4 months. The Alert Level remained at 3 (on a scale of 1-4). Residents and tourists were reminded not to approach the crater within a radius of 2.5 km.
